Periodontal ligament injection: an evaluation of the extent of anesthesia and postinjection discomfort
JE D'Souza,

The effects of a periodontal ligament (PDL) injection were evaluated as to whether the injected tooth alone or adjacent teeth were anesthetized. Results of the study indicated no difference in anesthesia achieved from pistol-pressure or standard-grip syringes, and determined what effects the type of syringe and solution injected had on the spread of anesthesia and the degree of discomfort felt during and after the injection.
